i have seen a few xx9 R exhausts for sale. are they any different than a regular can?

Nope. And anyone selling a "R" exhaust for more than $50 just because it came off a R is BS.

If it is an '03 exhaust from the US, it does not have a cat in it, so it is different. The midpipe also did not have a cat in it for this year. This was an "extra" exhaust that came with the bike. The Euro models also carried this "extra" exhaust into the next years as well but the US version did not. If you want to be sure, ask the seller to take a good photo of the inside of the inlet pipe on the right, the cat is clearly visible, so it should not be there if it is the "R" extra exhaust.

so its a stocker minus cats? is that worth anything?

They are worth something - if it's off a 2003 and looks like a standard system with the small outlets as they're a factory supplied system with no cats. Only the 2003 999R came with those systems. There's not many of those around so if you want something a bit less rowdy than the Termi half system (assymetric) but which flows better then the 2003 999R half system is it. They're certainly louder than the standard, cat equipped, system. It would have "for race use only" stamped underneath if it's the real thing.

A standard 999R system with cats may have a larger diameter but I'm thinking it's just the same as the base and S model systems....45mm for the rear cylinder and 45 going to 50mm for the front cylinder. I think the 2004 onwards 999R had the standard cat system fitted from factory and in some countries came with a Termi half system in the crate.

Also make sure you have a deep sump model, if it's after 2004 you should be fine.
